To lall whom it mar/y con/067ml' Bei-t known; that LBERT E. KLINE..a CitfY zen of the United States, residing` at Sheldon,

eral use only a portion of the adjusting-nut is exposed and much difficulty is often experienced owing to the fact that a sufficiently firm grip cannot be obtained thereon in ad justing the wrench.

The object of thepresent invention is to provide a wrench in which the adjusting-nut is so located as not to interferewith the operation of the wrench and in which the entire periphery thereof is exposed so that a iirm grip can be secured thereon.

It also frequently happens that a wrench is employed in connection with a large number of the same-sized nuts; and a further object of the invention is to provide means whereby the jaws of the wrench can be clamped in a fixed position.

Y For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eiicecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is aview through the handle of my form of wrench. Fig. 2 is a transverse sectional view.

Corresponding and like parts are referred to in the following description and indicated in both the views of the drawings by the same reference characters.

M invention is illustrated in Fig. 1, in whichthe numeral l designates the iixed jaw of the wrench, which is rigidly secured to the hollow stock 2, on the outer end of which the handle 3 is located. The relatively movable jaw 4 of the wrench is made integral with a shank 5, which is slidably mounted within the hollow stock 2 and has its outer end contracted to form a threaded stem 6. At the outer end of the stock 2 the opening therethrough is enlarged to form a circular cavity, within which the cylindrical adj usting-nut 7, which cooperates with the threaded stem 6, is located. The outer end of the cylindrical nut 7 projects from the end of the handle and is provided with a knurled head 8, upon which the operator can obtain a secure grip in adprovements in Wrenches, of which the followjustllgfthe Wrench, The outersurface of the.

ladjustng-nut. 7 is provided with an groove 9, wlflich coperateswith the end of a screw 10, which passes through thehandle to f hold nut 7 in position.

rllhis invention alsoprovidesmeans for lock-Y ing-the jaws 0f the Wrench-i` in a xed petition..

The stem 6 4et the enter end et the 5- is provded with a longitudinal; Opening ll, formed with broken @segmental threads 12?,v g which preferably run in an opposite direction to those upon the adjustingenut 7 A screw 18, passing Centrally through the cylindrical, nut and; havingy a thnmb-peee 14 at its outer; lend, is provided with similar broken or segmental threads, which cooperate with those in the opening 11.

It will be readily understood that the jaws of the wrench can be moved to any desired position with relation to each other by turning the knurled head 8, and attention is again directed to the fact that owing to the peculiar construction of the cylindrical adjusting-nut 7 the same is enabled to be made of such a length as to eliminate all danger of the stripping of the threads, which has heretofore caused considerable annoyance in wrenches of this type. In order to lock the jaws of the wrench in a fixed position, the screw 13 is then turned so that the broken or segmental threads do not engage with each other and is pushed into the thumb-piece 14 until it strikes against the knurled head 8. The wrench can then be rigidly locked in position by turning the thumbpiece 14 so that the segmental threads are brought into engagement with each other, It will be apparent from the drawings that the screw 13 can be readily removed from the wrench when desired and is not rigidly secured thereto.

Having thus described the invention, what is claimed as new is- 1. In a wrench, the combination of a fixed jaw rigidly secured to a hollow stock, the opening through the stock being enlarged at the outer end to form a cylindrical chamber, a relatively movable jaw connected to a shank which is slidably mounted within the hollow stock, the outer end of the shank being threaded, a cylindrical adjusting-nut located within the-before-mentioned chamber and coperating with the threaded portion of the shank, said adjustingnut having a thumb-piece projecting from the end of the stock, and means for locking the adjusting- IOO nut to the shank upon which the movable jaw is mounted to hold the jaws in a iixed position. l

2. In a wrench, the combination of a iiXed jaw rigidly secured to a hollow stock, the Opening through which is enlarged at the outer end to form a cylindrical chamberI a relatively movable jaw connected to a shank which is slidably mounted within the hollow stock7 the outer end of the shank being threaded and provided with a longitudinallydisposed threaded opening, a cylindrical adjusting-nut located in the before-mentioned cylindrical chamber and coperating with the threaded shank on the movable jaw, said adjusting-nut having a -head which projects from the end of the stock, and a screw passing through the cylindrical nut and coperating with the threaded opening in the shank to lock the jaws in a iixed position.

3. In a wrench, the combination of a fixed jaw rigidly secured to a hollow stock, the Opening through which is enlarged at the Outer end to form a cylindrical chamberI a relatively movable jaw secured to a shank which is slidably mounted within the hollow stock and has its Outer end threaded and provided with a longitudinal opening formed with broken or segmental threads which run in an Opposite direction to those on the Outer face of the shank, a cylindrical adjusting-nut located within the before-mentioned chamber and cooperating with the threaded shank y secured to the movable jaw, said adjustingnut having a head which projects from the end ofthe stock7 and a screw passing through the adj usting-nut and provided with a thumbpiece and with segmental Or broken threads which coperate with the before-mentioned segmental threads to lock the jaws Oi' the wrench in a fixed position.

In testimony whereof I aix my signature in presence of two witnesses.
